using the bypass vavle will almost always negate any gain you get from the cold air. if you plan on puttin ght by pass vavle, just get short ram.
This guy has a great idea, and it will save you 150 bucks...I don't know man, sounds good.
I swear, some people on here are just hilarious...You shouldn't even let the thought of buying a bypass valve in your head, it's a piece of junk and cuts your gain. Now of course the CAI sucks in cooler air (of course it does, look at the damn name), but the short ram sucks in more at higher rpms plus you won't have to worry about hydrolocking. Get a short ram intake, really doesn't matter what brand, throw a K&N Filter on it, and you'll be just fine.
Once you're moving, starting at about 40 mph, the ambient air temp in the engine bay is the same, people have tested this before by putting thermometer by their intakes. CAI are basically a waste of money.
